The largest star that we know of is called VY Canis Majoris it’s a long way from Earth between 3,900 and 5,000 light years.
It’s so big if it was the Sun in our solar system its surface would extend past Jupiter.

How big is the biggest star?
The largest stars, in contrast, will be cool supergiants. Case in point, VY Canis Majoris is only 3,500 Kelvin, and a really big star would be even cooler. At 3,000 Kelvin, Humphreys estimates that cool supergiant would be as big as 2,600 times the size of the Sun.
Which is bigger Uy scuti or VY Canis Majoris?
The answer is no, they are two completely different stars. VY Canis Majoris is considerably closer to the Earth compared to UY Scuti. Currently, UY Scuti is the largest star known, at an estimated radius 1708 times the size of the Sun’s.
Is there any star bigger than Uy scuti?
On a stellar scale, it’s really quite average — about half of the known stars are larger; half are smaller. The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.
What is the largest known object in the universe?
For years, astronomers were convinced that a structure known as the Sloan Great Wall was the biggest-known structure in the universe. This vast cluster of galaxies and other cosmic matter is a mind-boggling 1.4 billion light-years across. But just recently they found something even bigger.
What is the largest black hole?
Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say. The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus.
Can we see VY Canis Majoris from Earth?
But it’s not the largest. That distinction goes to another star in the Big Dog, VY Canis Majoris, a hypergiant star located about 3,800 light-years from Earth. If we could shrink the sun down to the size of a baseball, VY Canis Majoris would be a globe measuring 402 feet (122.5 meters) in diameter!
Who is the biggest star in the world?

How many times bigger is Uy scuti than the sun?
In terms of sheer physical size, the star UY Scuti is considered the biggest known. It’s only 30 times the sun’s mass, but has a radius more than 1,700 greater than the sun.
What is the brightest star?
The brightest star in the sky is Sirius, also known as the “Dog Star” or, more officially, Alpha Canis Majoris, for its position in the constellation Canis Major. Sirius is a binary star dominated by a luminous main sequence star, Sirius A, with an apparent magnitude of -1.46.
How far away is Uy scuti?
5,219 light years
What is the most massive star known?
Although R136a1 is the most massive known star, it is not the largest, since it only stretches about 30 times the radius of our sun. The largest known star is UY Scuti, a hypergiant with a radius somewhere around 1,700 times larger than the sun.
What is the biggest planet in the universe?
What’s The Largest Planet In The Universe?
- The exoplanet Kepler-39b is one of the most massive ones known, at 18 times the mass of Jupiter, placing it right on the border between planet and brown dwarf.
- A cutaway of Jupiter’s interior.
- WASP-17b is one of the largest planets confirmed not to be a brown dwarf.
What is the largest non gas planet?
In May 2014, previously discovered Kepler-10c was determined to have the mass comparable to Neptune (17 Earth masses). With the radius of 2.35, it is currently the largest known planet likely to have a predominantly rocky composition.
What is the heaviest thing on earth?
The heaviest object ever directly weighed was the Revolving Service Structure (RSS) of launch pad 39B at NASA’s Kennedy Space Center, Florida, USA. The structure was lifted up on 21 jacking points which, between them, measured the mass of the RSS as 2,423 tonnes (5,342,000 lbs).
What’s bigger than the universe?
The universe was already far too big to understand. But scientists just found that it’s actually much bigger than we’d previously thought. The observable universe is made up of at least two trillion galaxies, according to a new study. That’s 20 times more than had previously been thought.
What is a white hole NASA?
In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape.
What is the oldest black hole?
The related black hole of the quasar existed when the universe was about 690 million years old (about 5 percent of its currently known age of 13.80 billion years). The quasar comes from a time known as “the epoch of reionization”, when the universe emerged from its Dark Ages.
Do black holes die?
Answer by Frank Heile, P.h.D. Physics, Stanford University, on Quora: Black holes have a finite lifetime due to the emission of Hawking radiation. However, for most known astrophysical black holes, the time it would take to completely evaporate and disappear is far longer than the current age of the universe.
How far is VY Canis Majoris from Earth?
4,892 light years
Is VY Canis Majoris the same as Sirius?
Canis Major contains Sirius, the brightest star in the night sky, known as the “dog star”. It is bright because of its proximity to the Solar System. The red hypergiant VY Canis Majoris is one of the largest stars known, while the neutron star RX J0720.4-3125 has a radius of a mere 5 km.
Why is the Pistol Star Blue?
The Pistol Star is a blue hypergiant star; one of the most luminous known in the Milky Way. It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region. The star owes its name to the shape of the Pistol Nebula, which it illuminates.
Is the sun brighter than Sirius?
Sirius A is about twice as massive as the Sun ( M ☉) and has an absolute visual magnitude of +1.42. It is 25 times more luminous than the Sun but has a significantly lower luminosity than other bright stars such as Canopus or Rigel.
What is the brightest object in the universe?
Although quasars appear faint when viewed from Earth, they are visible from extreme distances, being the most luminous objects in the known universe. The brightest quasar in the sky is 3C 273 in the constellation of Virgo.
How much brighter is the Sun than the moon?
The apparent magnitude of the Sun is −26.74 (brighter), and the mean apparent magnitude of the full moon is −12.74 (dimmer). Difference in magnitude: Brightness factor: The Sun appears about 400000 times brighter than the full moon.
How hot is the Uy scuti?
Is our sun the biggest star in the universe?
VY CMa is described as the largest star in the Milky Way although galactic red supergiants above are possibly larger but they have less accurate radius estimates.
How did VY Canis Majoris get its name?
The first known recorded observation of VY Canis Majoris is in the star catalogue of the French astronomer Jérôme Lalande, on 7 March 1801, which lists it as a 7th magnitude star. It was given the variable star designation VY Canis Majoris in 1939, the 43rd variable star of the constellation Canis Major.
Why are there no green stars?
There are no truly green stars, because the color of a star is more or less given by a black-body spectrum and this never looks green. However, there are a few stars that appear green to some observers. This is usually because of the optical illusion that a red object can make nearby objects look greenish.
What kind of star is r136a1?
R136a1. RMC 136a1 (usually abbreviated to R136a1) is a Wolf–Rayet star located at the center of R136, the central concentration of stars of the large NGC 2070 open cluster in the Tarantula Nebula.
Which star is the most luminous?
Alpha Centauri A
